[. . . ] Installation manual T4250 / T4350 487 14 22 21. 07 GB Tumble dryer 3 Safety instructions This machine is only intended for drying water-washed garments. Clothes that have been cleaned with chemicals/inflammable liquids, must NOT be dried in the machine. Remove clothes from the tumble dryer as soon as they are dry. This prevents them from becoming creased, and reduces the risk of spontaneous ignition. [. . . ] Then the air flows out through a lint filter positioned immediately in front of the ventilator. After this, the air is evacuated through the ventilator and evacuation system. It is very important that the dryer gets enough fresh air, see next section. 1 Fresh-air Fig. 2 For maximum efficiency and the shortest possible drying time, it is important to ensure that fresh air is able to enter the room from the outside in the same volume as that blown out of the room. 3 To avoid a draught in the room, it is advisable to place the air inlet behind the dryer. The area* of the air inlet opening must be 5 times the size of the vent pipe area. The resistance in the grating/slats on the air inlet cover plate should not exceed 10 Pa (0. 1 mbar). *The area of the inlet opening is the area through which the air can flow without resistance from grating/slatted cover. Note that gratings/slatted covers often block half of the total fresh air vent area. Remember to take this into account. 2 A 5xA XXXX X 24 05. 01 487 19 3 5xA 487 14 22 21 - 4250/4350 GB Installation manual Evacuation system for installation of several machines with a shared evacuation pipe Evacuation pipe Fig. 1 It is recommended that each dryer be connected separately to a smooth air outlet pipe with the lowest possible friction. For safety reasons it is important that the dryer is connected to a smooth evacuation pipe with a 200 mm diameter. When installing several machines on shared evacuation pipe, increase the area of the pipe with each additional machine so that each dryer will be working at the same air resistance. Fig 1 and the below table show in simplified form how the evacuation pipe should look. 1 15 2 The outlet The pipe must end outside in the open. The outlet must be protected against rain and foreign objects. In cold areas, condensation may cause frost damage to the building. Installation in frigid laundries In frigid laundries and where the air resistance is very low it can be a problem to reach 12°C within the given time (Error code E18 will be displayed). In this case it will be necessary to throttle the outlet air on the damper in the evacuation pipe. Gentle bends Fig. To keep the air flowing, ensure proper dryer operation, and minimize lint build-up in the exhaust system, never connect ducts at right angles, always use gentle bends. The evacuation pipe diameter must not be reduced. 5 400 6 450 7 475 8 500 9 535 10 560 No. By opening / closing the damper B the static pressure at A is either lowered or raised. 1 120 Table with static pressure The optimum air volume is achieved if the pressure is adjusted according to the table below.

In these cases the damper must be closed as much as possible. The static pressures in this table are not to be mistaken for the counter-pressure from the pressure drop curve. 487 14 22 21 - 4250/4350 GB Installation manual Steam installation Before start The steam pipe must be cut off and must not be under pressure. 19 Steam Steam 3-10 bar absolute pressure (130180°C). 5 a b Steam forward 1.
